Optical slip ring apparatus is disclosed in which radial light signals formed in a continuous ring are transmitted between a barrel and a surrounding sleeve within which the barrel is rotatably mounted. The ring of light signals is produced and detected respectively by a plurality of light emitting diodes and light detector means carried on the barrel and the sleeve. The light detector means may include an optical fiber bundle for transmitting light signals to a remote detector. In one embodiment, a plurality of optical and electromechanical slip ring channels are incorporated into a single device.

Optical slip ring apparatus for transmitting light signals between two bodies, one of which is rotatable relative to the other about an axis of rotation, comprising: a first light source for emitting a first radial light signal throughout a continous ring in a first plane; a first member adapted to be fixed to one of the relatively rotatable bodies, and adapted to carry said first light source so that said ring is centered on the axis of rotation and the first plane is perpendicular to the axis of rotation; a first light detector; and a second member adapted to be fixed to the other of the relatively rotatable bodies, and adapted to carry said first light detector so that it is positioned to receive radial light signals emitted by said first light source.
